Hyperostosis in Fishes: An Update With New Species Records
Journal of Morphology, Volume 285, Issue 11, November 2024.Hyperostosis is an enigmatic dimension of diversity in the anatomy of fishes. This excessive overgrowth of bone is natural in origin, occurs almost exclusively in marine fishes, is generally species‐specific, and becomes fully developed only in large individuals. We document hyperostosis in 35 families, 89 genera, and 153 species.

A multiscale perspective for improving conservation of Conchos pupfish
Animal Conservation, Volume 27, Issue 4, Page 538-553, August 2024.We evaluated the abundance and distribution of Conchos Pupfish across multiple spatial scales in Mexico and the United States to develop scale‐dependent conservation opportunities. Conservation opportunities guided by this work include future survey locations and establishment of protected areas at the basin scale (105 m extent), maintenance of ...
